Abstract

본 발명은 차량이 급발진하게 될 때에 과도한 연료공급을 차단하여 엔진의 회전수를 적당하게 조정할 수 있게 하는 차량의 과도 연료차단 드레스홀드 회전수제어장치에 관한 것으로, 한 개의 상수로 제어하는 종래의 장치는 엔진이 공회전상태에서 드로틀밸브의 최대열림상태까지 급발진할 경우에 연료가 차단되어도 짧은 시간동안에 엔진 회전수가 급상승하게 되기 때문에 엔진의 관성력을 통해 최대회전수까지 엔진의 회전수가 상승하게 되는 문제가 있었던 바, 공회전상태에서 드로틀배리브 최대열림상태까지의 시산변환에 따른 드로틀밸브 위치센서의 감지값과 엔진 회전수(Engine RPM)의 변화값을 통해 과도 연료차단후의 엔진의 회전수를 결정할 수 있도록 하는 것을 특징으로 하는 본 발명에 의하면 두개의 변수를 통해 회전수를 조정함으로써 차량의 급발진시에 엔진이 과도하게 회전하는 것을 방지할 수 있게 되므로 엔진의 손상을 최대한 억제할 수 있게 될 뿐 아니라 차량의 수명을 크게 연장시킬 수 있게 된다.The present invention relates to a transient fuel cut-off dress hold rotation speed control device for controlling the engine speed by blocking excessive fuel supply when the vehicle suddenly starts, the conventional apparatus for controlling with one constant When the engine suddenly starts up to the maximum open state of the throttle valve in the idle state, the engine speed increases rapidly for a short time even if the fuel is cut off, so that the engine speed increases to the maximum speed through the inertia of the engine. Bar and engine speed after transient fuel shut-off can be determined through the detection value of the throttle valve position sensor and the change of engine RPM according to the time conversion from idle to maximum opening of the throttle barrel. According to the invention characterized in that the difference by adjusting the rotation speed through two parameters It is possible to prevent the engine from rotating excessively during the sudden start of the amount, it is possible to suppress the damage of the engine as much as possible and to greatly extend the life of the vehicle.

Claims (1)

차량의 과도연료차단 드레스홀드회전수 제어방법에 있어서, 엔진의 공회전상태로 부터 드로틀밸브 최대열림상태까지의 시간변화에 따른 드로틀밸브의 개방도 및 시간변화에 따른 회전수의 변화도에 의해 엔진의 급발진여부를 판단하고, 엔진의 급 발진으로 판단되었을 때 미리 정해진 값을 드레스홀드회전수를 결정하는 것을 특징으로 하는 차량의 과도연료차단 드레스홀드 회전수제어방법.In the method of controlling excessive fuel cut-off dress hold rotation speed of a vehicle, the engine is controlled by the opening degree of the throttle valve according to the change of time from the idle state of the engine to the maximum opening state of the throttle valve and the change of the rotation speed according to the change of time. And determining the sudden start of the engine and determining the dresshold rotation speed based on a predetermined value when it is determined that the engine is suddenly started. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
